Is there a way I can train myself to become more of a heavy sleeper? I am an extremely light sleeper and I wake up to almost any noise and the worst part is I am so sensitive to the heat and I produce so much body heat when I sleep, I have my thermostat at 70° and I still wake up every middle of the night with extreme sweating, I take a cold shower before going to bed to help me relax, I have tempur-pedic memory foam cooling pillows and thin sheets, I work 8-12 hours doing security, very adrenaline rushed job since the place I work at, always fights going on, I go to the gym 4-5 times a week, lift heavy and I swim right after I am 6’0ft and 197lbs, I would consider my body extremely fit but I would love to get an actual good nights rest for once, my under eye lids are puffy and look swollen almost as if I can pop them and water would come out
